Abstract
The utility model discloses a flexible anti-galloping interval stick of a transmission line. The flexible anti-galloping interval stick comprises a compound insulator, conducting metal fittings are arranged at the both ends of the compound insulator, the compound insulator is formed by hinging the head and the tail of a certain number of compound insulator unit bodies, moreover, equalizing rings are arranged at the outer end part of the two compound insulator unit bodies at the both ends, and the equalizing rings are connected with the conducting metal fittings at the identical end through a flexible conductor; two or more than two compound insulator unit bodies are provided, a stitch and a needle cap are respectively arranged at the both ends of the compound insulator unit bodies, wherein, the outer end of the stitches adopt a flat plate, the outer end of the needle caps adopt a flat groove, the outer end of the stitches of the adjacent insulator unit bodies and the outer end of needle caps are spliced and are connected through bolts, and can be rotated. The flexible anti-galloping interval stick can effectively prevent the wave of split conducting wires.
Description
Technical field:
The utility model relates to the transmission line anti-bouncing spacer, and particularly the transmission line flexible anti is waved inter-phase spacer, belongs to the device of transmission line technical field.
Background technology:
Transmission line wire is waved the safe operation that electric power system in serious threat, has become the main harm of the normal operation of circuit in some countries and regions.Conductor galloping just took place as far back as nineteen fifty-seven in China, though happen occasionally later on but do not cause very big concern, the line fault on a large scale that leads to because of conductor galloping has several times taken place up to 1985,1998,2003, caused serious consequences such as large-area power-cuts, caused that just power department payes attention to widely.Trip when avoiding transmission line galloping, cause electric power accident, need to adopt the anti-device of waving.Pressing down the dance measure is that generation is waved in a kind of inhibition or control is waved scale, weakened a class measure of waving intensity, mainly be to suppress the amplitude of waving by anti-dancing device is installed on the line, thereby the purpose that harm reaches anti-dance is waved in elimination, and the main method of taking is at present: off resonance pendulum, inter-phase spacer etc.
Inter-phase spacer prevents that conductor galloping from all having a wide range of applications at home and abroad, also has a large amount of successful examples and experience.At present, generally the sub-lead spacer of Cai Yonging is made up of barred body and wire clamp, wire clamp connects barred body and sub-conductor constitutes bundle conductor, wire clamp and barred body rigid connection, with the fastening connection of sub-conductor, the rotation of constraint sub-conductor in wire clamp makes the torsion angle of sub-conductor under the aerodynamic couple effect reduce along shelves length direction rate of change, thereby make the aerodynamic couple that acts on the sub-conductor reduce, and then bring out built on stilts bundle conductor and wave along shelves length direction rate of change.The inter-phase spacer of Cai Yonging was that early employing also is the device that comparatively is usually used in preventing conductor galloping in the past, but the diameter of mandrel of inter-phase spacer in the past is the important parameter of its mechanical property of decision, diameter of mandrel is big more, its ability of bearing pressure is strong more, the support force that can produce is big more, therefore also can hinder the close mutually of adjacent wires more, everybody thinks that effect is good more.But diameter of mandrel is big more, and its deadweight is also big more, will produce big centralized load to lead when installing on the line, increases the static stress and the sag of lead, is unfavorable for the safety of circuit, and this has become an outstanding problem in the inter-phase spacer application.To its anti-dance function influence effect, lack the corresponding argumentation of documents and materials about the inter-phase spacer bearing capacity,, the inter-phase spacer diameter of mandrel greatly might be reduced so fully, more lightness if bearing capacity is little to the influence of anti-dance effect.
The utility model content:
Technical problem to be solved in the utility model is: bring out the deficiency that the overhead power transmission bundle conductor is waved for the fastening connection that overcomes wire clamp and sub-conductor, provide a kind of transmission line flexible anti to wave inter-phase spacer.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of transmission line flexible anti is waved inter-phase spacer, contain composite insulator, and the two ends of composite insulator are provided with the conduction gold utensil, described composite insulator is by hinged the forming of composite insulator cell cube head and the tail of some, and the outer end of two composite insulator cell cubes at two ends is provided with grading ring, and described grading ring connects with the conduction gold utensil of holding together by flexible conductor.
The quantity of described composite insulator cell cube is two, or be more than two, the two ends of each composite insulator cell cube are respectively arranged with a steel pin and steel cap, wherein, the outer end of steel pin is a flat board, the outer end of steel cap is one rises as high as the banks, and pegging graft with steel cap outer end and be connected by bolt in the steel pin outer end of adjacent composite insulator cell cube, can rotate.
The quantity of described composite insulator cell cube is three, or is four.
Transmission line flexible anti of the present utility model is waved the inter-phase spacer characteristics: flexible structure, and light weight, easy for installation, cost is more cheap, and have the effect that anti-fatigue ability and good inhibition are waved; Heterogeneous isolated lead can be associated together, utilize factor such as the asynchronous swing of adjacent wires to suppress to wave, guidewire movement is played damping anti-dance action usefulness, can effectively prevent waving of bundle conductor.
